DTC P0758 2-3 Shift solenoid 2000 Chevy Blazer

I have a 2000 Chevy Blazer and recently it started accelerating slow from a stop and the check engine light came on. The code it gives is the P0758 2-3 shift solenoid malfunction. I know how to troubleshoot it and what may need to do to replace it but I cant find any electrical diagrams for the ecu or any ohm specs for the solenoid and corresponding components. Can you please help me?

    I know its in the transmission but the code calls for a short or open in the circuit so i need to check the ecu too i just need to know where on which connector?

    Get yourself a factory service manual, that is the only way you will fix this, u do know the shift solenoid is inside the transmission?

2009 Chevy Silverado P2138 Accelerator Pedal Position


Circuit/System Description
The throttle actuator control (TAC) system uses two accelerator pedal position (APP) sensors to monitor the accelerator pedal position. The APP sensors 1 and 2 are located within the pedal assembly. Each sensor has a 5-volt reference circuit, a low reference circuit, and a signal circuit.
Two processors are also used to monitor the TAC system data. Both processors are located within the engine control module (ECM). Each signal circuit provides both processors with a signal voltage proportional to pedal movement. The processors share and monitor data to verify that the indicated APP calculation is correct.

DTC P0455: Evaporative Emission (EVAP) System Large Leak

The control module tests the evaporative emission (EVAP) system for a large leak. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the EVAP system vacuum level. When the conditions for running are met, the control module commands the EVAP canister purge solenoid valve OPEN and the EVAP vent solenoid valve CLOSED. This allows engine vacuum to enter the EVAP system. At a calibrated time, or vacuum level, the control module commands the EVAP canister purge solenoid valve closed, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum level. The following table illustrates the relationship between the ON and OFF states, and the OPEN or CLOSED states of the EVAP canister purge and vent solenoid valves.

Trail blazer gear shift button


Could be the brake switch or the shift lock solenoid. You may be able to turn the key lock to the unlock position, move the shifter out of park, then start the engine in neutral.
The shifter and the shift lock solenoid would need to be inspected.

1997 chevy blazer 4*4 will not go into reverse , drives and shifts sluggish in forward gears . parked overnight went to back up the next morning and vehicle was like neutral in reverse. fluid level is ok .


You may have a bad revers solenoid. Check the fuse and look for any of the fuse to be bad like the transmission fuse. Best thing to do is get the blazer scanned at Auto Zone free of charge for any DTC codes that may be affecting your transmission's performance. Try this, place the ignition to the run position and pull the ECM(BATT) fuse out for 30 seconds and then place it back in. Start the Blazer, it may stall but let it. Just start it again the ECM is just relearning the engine and transmission, let it idle for 1 min and then go for a test drive. This should reset everything in the truck's ECM like the day it was first started and any DTC code will be new and active. Do not add any additives like lucas transmission fluid repair, that will just make it worst. Any additive that may the transmission thicker will make the fluid retention more making the shift solenoid stick causing shift conflicts. Good luck and keep me posted. No revers is ether a bad solenoid, bad PCM signal, or broken sun gear.

I Have a 2002 blazer that starts but motor dies, surges when accelerating


If this engine is a VORTEC then you may have a problem with the internal fuel system. Under the top plenum there is a fuel reg and poppet valves that inject fuel into the cylinders. Sometimes the tubes that run fuel from the reg to the valves can leak and cause your problem. This cannot be found with pressure check because this occurrs after the reg. PS fuel mileage will go down. Let me know if this helps.Moe
